TRANSMISSION OF INTERNET PACKETS ACCORDING TO A PRIORITY

摘要

When changing affiliation from a first packet data network to a second packet data network (Sl), a mobile node (31) is operable to generate a service level identifier (37) representing a requested priority (S2) to be afforded to the internet packets communicated to and from the mobile node. The mobile node is also operable to generate a binding update internet packet (35) providing a care of address of the mobile and an indication of the service level identifier (S2) in the binding update internet packet and to communicate the binding update internet data packets to a home agent (S3) of the mobile node. The home agent is operable in response to the binding update to identify the service level identifier (S4) and to communicate the internet packets in accordance with the requested priority (S5) represented by the service level identifier.
